New for 2013! Many of the best teams in college and high school softball were swinging the Louisville Slugger TPS Xeno this past year! That's because they learned the old fashioned way which bat was the hottest: through thousands of hours of practice and play. The dedication that Louisville Slugger put in to create the Xeno design really shines through in this year's model, and it all starts with S1iD Technology. This technology actually allows the barrel to be tuned to exceed the legal ball exit speed ratio. The catch is that a governor is placed inside that allows the barrel to flex to its MAXIMUM allowable performance from SWING 1. The Xeno is made from Louisville Slugger's innovative new LS 2X Composite, yet due to the S1iD technology, it needs ABSOLUTELY ZERO BREAK-IN! The Xeno features an iST design that gives this bat a solid connection between the barrel and handle. iST provides players a bat with a solid feel and HUGE sweetspot, while absorbing vibrations from mis-hit balls before they reach the hands. With a tacky synthetic grip a 7/8 inch handle, the Xeno will give players absolute control at the plate. If you are a fastpitch player looking for THE top-of-the-line bat this season, look no furthur than the TPS Xeno! Louisville Slugger: In a Class Above Any Other! The Xeno is approved by ASA, USSSA, NSA, ISA and ISF. This bat comes with a Full Twelve (12) Month Manufacturer's Warranty.
